Abstract
The invention relates to a DC-DC converter, which includes a power stage driven by a pulse width modulator, a first error amplifier with a first input coupled to a first reference voltage source and a second input coupled to a current sink through which a current is fed from an output of the power stage to receive a first feedback voltage (FB), a second error amplifier with a first input coupled to a second reference voltage source and a second input coupled to the output of the power stage to receive a second reference voltage (FB), and switching means (SW) for connecting a control input of the pulse width modulator with the output of the first error amplifier in a current regulation mode and with the output of the second error amplifier in a voltage regulation control mode.
